Been reading and searching but can't seem to find a graph. If there is one..

The articles I've been reading talk about balancing your Calc and Alk. I was just wondering if there was a graph for desired levels. Or is it as long as your within the desired targets your good? For example I tested my water tonight.

My reading were
Cal = 465ppm
Alk = 6.4dKh
MAG = 1500ppm
Sal = 1.025

I know my Alk is a little low and the target should be between 7-11 dKh. But with my Calc being at 465ppm what should my target for ALK be?

So I'm wondering if there is a graph with all the different targets on them.

Gary thanks for links. I had those 2 jewels bookmarked already from your suggestions awhile ago. The calculator is great and I use it all the time.

But let me see if I can explain what I mean better. If someones Calc is say 500ppm would it be more beneficial to have your Alk at 7dKh or 11dKh? Or is it really just a matter of hitting the desired targets.

My understanding was say my Calc was at 380ppm so I should target my Alk at 7dKh. If my Calc were 485ppm I should target 11dKh? Is that right or is there no real benefits to that?

Maybe as long as someones Alk is between 7 -11 dKH they are fine regardless of the level of their Calc. Does my rambling make any sense? I'm just trying to fully understand this or am I being to neurotic?

correct.
Balanced levels of alkalinity and calcium are desirable in a reef aquarium.
The benefits of being able to provide correct and stable parameters is the amount of sensitive biodiversity one can maintain in their aquarium.
